Wireless Vision Leads to New Focus, New Products, New Company

For more than 30 years, California Microwave has signified technical excellence, strong support and solid value. Over the past two years, it has sharpened its market and product focus to concentrate on wireless broadband solutions.

Guided by a vision of the wireless future, where access to information is immediate, untethered and geographically unlimited, an exciting new, shareholder-friendly company has emerged.

California Microwave has realized its vision with a new set of products that reflect its focus and product strategy, and has divested all businesses that do not pertain to its strategic focus.

The company has added to its comprehensive wireless product portfolio newly developed solutions in Wireless Broadband Access, Digital Broadcast TV, Satellite Broadband IP Transport, and Wireless Online Transaction Processing.

These additions are complementary to its market-leading products in the data satellite, terrestrial wireless data telemetry and terrestrial wireless analog video areas. These four new product areas will be featured at the product showcase on April 29.

AB-Access Offers Bandwidth Management Superior to XDSL, Cable

Modems

AB-Access is a key component of California Microwave's April 1998 strategic initiative plan that focuses company resources on delivering end-to-end Wireless Broadband Solutions for telecommunications and service providers world-wide. The patented design of the AB-Access MAC layer uniquely provides service companies with an instant provisioning capability and customers with portability for Internet and other data needs.

As data traffic overtakes voice traffic, providers are moving away from dedicated circuit-based, to packet-based network infrastructures. Packet-based networks offer providers an efficient method to supply Internet, data, video, and multimedia applications over the same infrastructure.

The "packet-on-demand" aspect of the AB-Access system fits well within this infrastructure shift and offers higher data rates (up to 25 Mbps) and superior bandwidth management than competitive alternatives, such as XDSL and cable modems.

On April 29, California Microwave will demonstrate simultaneous video conferencing, full-motion streaming video and high-speed connections to the Internet over a single connection, at speeds 450 times faster than conventional modem networks.

California Microwave, Inc. (http://www.calmike.com) is a leading supplier of terrestrial wireless and satellite-based systems to support ultra-high speed Internet access, broadcast digital TV transport and worldwide Internet backbones. California Microwave also provides industry-leading solutions for satellite-based data communications and terrestrial wireless telemetry networks.

With its emergence as a leading architect of the wireless broadband evolution, California Microwave will change its name to better express this new identity. Effective April 29, 1999, it will become Adaptive Broadband Corporation (ADAP). -0-
